Enginetech BC455J030 Main Bearings GM 3.8L 231 7/16" Main BoltS

Enginetech Rod & Main Bearings Enginetech main & rod bearings - the choice of rebuilders for over 25 years. About ten years ago, when aluminum bearings were first being introduced, Enginetech continued to produce the higher quality tri-metal 780 bearings. Enginetech stuck firm with the 780 tri-metal material for years because it was far superior to the early aluminum bearing technology. Advanced technology in the last few years has produced huge improvements in aluminum bearings. The additions of high amounts of silicon dispersed within aluminum alloys have moved aluminum-silicone bearing material to the preferred bearing status. The performance of new aluminum-silicone alloys is now equal to or better than the original tri-metal designs. Due to the new advances in aluminum-silicon bearing technology Enginetech is converting most of our main & rod bearings to the advanced aluminum-silicon material.

Clevite MS-2328P Engine Crankshaft Main Bearing Set

Ideal for rebuilding engines where more demanding use is anticipated, such as heavy duty, motorsports, or street performance. As it is the most versatile replacement engine bearing, P-Series is suitable for most OE applications. Due to the increased load capacity of the TriMetal design, it is a suitable upgrade from Bimetal engine bearings.

Features

Manufactured from cast copper-lead, increases fatigue strength by approximately 20% compared to powdered metal processes, referred to as sintering, which is used by the competition

Provides a margin of forgiveness for vehicles that don't get maintenance service as often as they should
